36、ual zones across the width of the fabric. One specimen for each required test shall be taken from each zone.b. Samples from membrane rolls greater than 80 in. (2.0 m) wide shall be divided into four equal zones across the width of the fabric. One specimen for each required test shall be taken from e

37、ach zone.c. When testing fabrics, specimens for the same physical test taken from the different zones across the width of the fabric shall be laid out so that they do not include the same warp or fi ll yarns.2.3.2 ConditionsCoated fi berglass shall be tested in both wet and dry conditions. The wet t

38、ensile test shall be performed with the same size specimen as the dry tensile test. The specimen shall be fully immersed in water, exposing the open edges and face to the potential invasion of water. The specimen shall remain submerged for 24 h. After 24 h, the specimen shall be removed, patted dry,

39、 and tested in the same manner as is done for the dry tensile test. The minimum result, to be indicative of proper coating and suffi cient protection of the yarn bundle, shall be 80% of the value obtained in the dry tensile test.2.3.3 FlexfoldCoated fi berglass shall be tested for fl exfold as descr

40、ibed in ASTM D4851.2.3.4 Biaxial TestingAs a minimum, biaxial testing shall be conducted by the material manufac-turer for the purposes of quality control at the follow-ing times:a. whenever a new manufacturing process is used andb. for each 100,000 ft2(10,000 m2). For membranes with a history of co

41、nsistent test results (coeffi cient of variation of 5% or less), the frequency can be reduced to every 200,000 ft2(20,000 m2).2.3.5 Uniaxial TestingAs a minimum, uniaxial elongation testing, as described in Section 2.4.1, shall be undertaken by the material manufacturer for every 10,000 ft2(900 m2)

42、of membrane used in the fi nished structure with a minimum of one test per roll. For membranes with a history of consistent test results (coeffi cient of variation of 5% or less), the frequency of testing can be reduced to every 50,000 ft2(5,000 m2) with a minimum of one test per roll. The number of

43、 specimens per sample shall be in accor-dance with Section 2.3.1.2.1 GENERAL2.1.1 MembranesMembrane materials used in the tensile membrane shall conform to and shall be tested in conformance with the requirements of this chapter. Other materials (e.g., cables, steel, aluminum, timber, and concrete)

44、shall conform to the requirements of their respective standards.2.1.2 QualityMembrane materials used in struc-tures shall be of uniform quality and shall have prop-erties required for the intended usage. The rolls of materials provided by the material manufacturer shall be marked to indicate any are

45、as with defects that would impair their structural integrity or serviceability.2.2 TESTING QUALIFICATIONSTests shall be performed by qualifi ed testing agencies or by qualifi ed employees of the material manufac-turer or membrane fabricator acceptable to the author-ity having jurisdiction. Manufactu

46、rers and fabricators performing their own testing shall demonstrate con-formance with the standards referenced in this chapter.2.3 PHYSICAL TESTING2.3.1 FrequencyMembranes shall have a published specifi cation that identifi es the minimum test values for the properties identifi ed in Section 2.4.1.

47、Testing frequency for physical properties of membranes shall be based on the surface area of membrane to be present in the fi nished structure. Unless otherwise specifi ed in this chapter, the required tests shall be performed for every 10,000 ft2(900 m2), or fractional part thereof, of membrane in

48、the fi nished structure. For membranes with a history of consistent test results (coeffi cient of variation of 5% or less), the fre-quency of testing can be reduced to every 50,000 ft2(5,000 m2). Except as limited by sample size of the specifi c test, the number of specimens per sample shall depend

49、on the membrane roll width:a. Samples from membrane rolls less than or equal to 80 in. (2.0 m) wide shall be divided into three TENSILE MEMBRANE STRUCTURES62.3.6 FrequencyThe frequency of testing may be increased as required by the architect or engineer of record. Such additional testing shall be clearly defi ned in the contract documents.2.4 PHYSICAL PROPERTIES2.4.1 GeneralMembrane physical properties shall be determined in accordance with ASTM D4851, except as modifi ed herein. As a minimum require-ment, testing as prescribed in Section 2.3 shal
